Maximum likelihood estimation for generalized autoregressive score models

Blasques, Francisco; Koopman, Siem Jan; Lucas, André - 2014

We study the strong consistency and asymptotic normality of the maximum likelihood estimator for a class of time series … processes. We formulate primitive conditions for global identification, invertibility, strong consistency, and asymptotic …

Asymptotic and finite sample properties for multivariate rotated GARCH models

Asai, Manabu; Chang, Chia-Lin; McAleer, Michael; … - In: Econometrics : open access journal 9 (2021) 2, pp. 1-21

This paper derives the statistical properties of a two-step approach to estimating multivariate rotated GARCH-BEKK … (2sQML) estimator, this paper shows consistency and asymptotic normality under weak conditions. While second …-order moments are needed for the consistency of the estimated unconditional covariance matrix, the existence of the finite sixth …

Estimating Multi-Equational Lqac Models with I(1) Variables : A VAR Approach

Fanelli, Luca - 1998

This paper extends the existing literature on linear quadratic adjustment cost (LQAC) models under rational expectations to the inferential issues arising when: (i) agents optimise with respect to a vector of endogenous variables; (ii) the behavioural equations stemming from the agent's...

Robust Detection of Multivariate Outliers in Asset Returns and Risk Factors Data

Green, Christopher G - 2017

It is well-known that outliers exist in the type of multivariate data used by financial practitioners for portfolio construction and risk management. Typically, outliers are addressed prior to model fitting by applying some combination of trimming and/or Winsorization to each individual...

Chapter 62 A Practitioner's Approach to Estimating Intertemporal Relationships Using Longitudinal Data: Lessons from Applications in Wage Dynamics

MaCurdy, Thomas - In: Handbook of econometrics : volume 6A, (pp. 4057-4167). 2007

This chapter presents a unified set of estimation methods for fitting a rich array of models describing dynamic relationships within a longitudinal data setting. The discussion surveys approaches for characterizing the micro dynamics of continuous dependent variables both over time and across...

Robust Estimation of Some Nonregular Parameters

Song, Kyungchul - 2010

This paper develops optimal estimation of a potentially non-differentiable functional Γβ of a regular parameter β, when Γ satisfies certain conditions. Primary examples are min or max functionals that frequently appear in the analysis of partially identified models. This paper investigates...

Factor Profiling for Ultra High Dimensional Variable Selection

Wang, Hansheng - 2010

We propose here a novel method of factor profiling (FP) for ultra high dimensional variable selection. The new method assumes that the correlation structure of the high dimensional data can be well represented by a set of low-dimensional latent factors (Fan et al., 2008). The latent factors can...

On a Principal Varying Coefficient Model

Jiang, Qian - 2012

We propose a novel varying coefficient model, called principal varying coefficient model (PVCM), by characterizing the varying coefficients through linear combinations of a few principal functions. Compared with the conventional varying coefficient model (VCM; Chen and Tsay, 1993; Hastie and...
